MEANS FOR CONTROLLING AND REVERSING VESSELS.

Application filed May 31, 1922, Serial No. 564,904. Renewed. August 26, 1924.

To all whom it may concern:

Be it known that I, Annnns JoHAN EMIL RYLANDER, a subject of the King of Sweden, residing at Katarina Kyrkobacke 2, Stock holin, in the Kingdom of Sweden, have in vented certain new and useful Improvements in Means for Controlling and Reversing Vessels, of which the following is a specification.

The present invention has for its object to provide improved means for controlling and reversing vessels without reversing the motive power agent.

For a consideration of what I believe to be novel and my invention, attention is directed to the accompanying specification, and the claims appended thereto.

In the accompanying drawings which are illustrative of my invention, Fig. 1 shows a side elevation of a rudder incollapsed posi tion; Fig. 2 is a top plan of the, said rudder in the same position; Fig. '3 is a front eleva tion of the rudder in intermediate position; Fig. 3 is a section of a joint in the rudder r on an enlarged scale; Fig. 4 is a top view of the rudder in the said intermediate position: Fig. 5 is a front elevation of the rudder in expanded position; Fig. 5 is a section of the rudder on the line W -5, 5, on a re duced scale; Fig. 6 is a top plan of the rudder in its expanded position; Fig. 7 shows a modification of the rudder in a position corresponding to that shown in Fig. 3; Fig. 8 is a view similar to Fig. 4 of a modification; Fig. 9 is a view in side elevation of thestern portion oi a vessel equipped with one form of my improved apparatus; Fig.-

10 shows a modification oi the steering and maneuverin transmission.

Similar numerals refer to similar parts throughout the several views.

Referring to Fig. 9. 1 indicates the stern portion of the hull of the vessel, which may be of any suitable or usual construction, and 2 a propeller carried by the shaft 3. The rudder, Figs. 1 to 6, comprises two rectangir lar side plates 4 and 5 and. a substantially.

U-shaped frame 6. A sleeve or tubular rudder post 7 is fixed to the upper horizontal portion 6 of the frame 6 and surrounds a part of a shaft or spindle 8. A crank 9 is fixed on the shaft 8 substantially in the height of the upper part 6 Connected with the crank 9 is a rod 10. The rod 10 is hinged to a slide 11, which slides on the frame part 6, and to which are connected two links 12 and 13. These links 12 and 13 are pivotally attached to flanged parts 14- and 15 of the plates 4 and 5. To the flanges 14 and 15 are by bolts 16 and 17 also hinged links 18 and 19, which on the other side are connected to a common head, which is slid: ably mounted on the slide 11. Rods 21 and 22 are hinged to the end of the frame part 6- by the bolt 23 and to flanges 14 and 15. Preferably the rods 21 and 22 are pivotally mounted on the bolts 16 and 17.

At the lower part 6 of the rudder there is a similar link system, indicated on the drawings by the same numerals.

Triangular shaped plates 24 are preferablyhinged to the upper and lower edges of the plates 4 and 5, as indicated at 25. The plates 24 are united in pairs by universal joints 26 consisting of a ball 26 and a housing in two parts 26 and 26, as shown in Fig. 3. To the upper plates 24 may be hinged, as indicated at 27, plates 28, supportingsleeve like parts 29, in which are slidable mounted plates 30 hinged, as indicated at 31, to the lower plates 24. Channels 32 are formed between the plates 4 and 5 0n the one side and the plates 28 and 30 on the other side. The plates 28 and 30 are shorter in horizontal direction than the plates 4 and 5, as shown in Fig. 5

The slide 11 has eyes 33 and 34. In the eyes 33 is carried a bolt and in the eyes 34 a bolt 36. The slide 11 is supported on the frame 6 by these bolts 35 and 36. The eyes 33 and 34 cooperate with the head 20 for the purpose hereinafter described.

Fig. 7 shows a modification in which the plates 24 in. lieu of inwardly, as indicated in Figs. 1 to 6. are directed outwardly. In this case the frame 6 must be dimensioned with its horizontal parts 6 and 6 aspaced from the plate construction, so as to permit the outward movement oi. the plates 24.

The crank 9 and the rod 10 may be substituted by a toothed wheel or pinion 37 and. a rack 38, as shown in Fig. 8, the other parts being of the same construction as is illustrated in Figs. 1 to 6.

Situated in the vessel is a steering wheel 39, Fig. 9, fixed on a shaft 40, which is journailed in a rigid part of the vessel. Bi 1i dly attached to the shaft lO are two sprocket wheels 41 and 5L2. The sprocket 4:1 is by means of a chain in drirlng' attachment with a wheel at secured to the r dder post The sprocket 42 is by the chain 45, the parts of Which cross themselves as at d5. connected with a sprocket 41:6 ri uidly secured to a bevel solar wheel t? in a differential gear 47, 4:8, 4:9, 50. In conjunction with and supporting the planetary wheels 48 and (that may be one, two or more in numeral) is attached a rim forming a sprocket wheel 51 (see also Fig. 10) having a tllliilfil'tl' twice that of the sprocket 4G and by the chain 52 in driving; combination with the wheel 53, fixed on the shaft 8. A sprocket wheel 54, fixed to the wheel 49.. by means of a chain connected to a sprocket wheel 56, which last mentioned wheel 56 is tired to a short shaft 57 turnably mounted in the vessel. The sprocket wheel 55 ca be retated by means of a handle 58. which is fixed in position by a pin 5., slidably nniunted in the handle and cooperating with a depression in a fixed part 59.

The operation of the arrangement is as follows:

Assuming the rudder being collapsed. Figs. 1 and 2., and the wheel 56 being fixed in position. On turning the steering: wheel 39 in one direction, the wheels ll and will be brought in rotation. The wheel 41 thereby, by means of the chain 43, rotates the wheel 44 and the rudder post 7. and the wheel 4-2 rotates the wheel ll The latter wheel 46, that is fixed to the solar wheel 1-7. causes rotation of the planetary wheels 4-8 and 50, which roll on the solar wheel 44), that is fixed in the vessel by the connection to the temporarily fixed wheel 56. The result is a rotation of the wheel. will half the velocity of the wheel 4-6. but as the wheel. 51 is twice in diameter of the wheel 4-5, the wheel 58 will be rotated with the same velocity as the wheel 44, supposed that the diameters of the wheels 41. a t and are dimensioned in relation thereto. Thus the rudder post 7 and the shaft 8 will be rotated in unison, bringing the rudder tofunctionate as a common steering rudder.

If on the contrary the wheel is fixed and the handle is rotated, the transmis sion 56, 55, 5-1, 4-9 will bring the wheels if? and 50 to roll on the now fixed wheel 4?. thereby causing the wheels 5l and and the shaft 8 to rotate. whilst the wheel 4.4, the rudder post 7 and the frame 6 are stag;- nant. In this case the crank 9, Fig. 2. turns and causes by means of the rod 10 the slide 11 to slide on the frame part (i forwiu'dly (in the ahead direction of the ship). whereby the plates at and 5 are forced to the sides the links 12 and 13. In an intermediate position, Figs. 3 and 4-, the eyes will come into contact with the head 20 and bring it and the links 18 and 19 to take part of the movement. Thus the plates at an end are brought in the position, shown in Figs. 5 and (5, in which the rear edges of the plates 4-, 5 and 24: come into contact with each other respectively, forming a pocket in which the water is forced to deflect and return. thereby causing the vessel to reverse. is the plates 28 and 30 are shorter than the plates 4: and 5, an opening 50 is formed between them, through which the water enters the channels 32 and then passes out in a forward direction without meeting; the water stream from the propeller. In that manner the forming of or dies is diminished. The movements of the plates 2% relatively to each other is iu-cordinpgly a double one, partly to a position in which they in pairs are nearly in plane with each other, which movement lasts during the whole expanding; procedurc.partly to a position in which their rear lllCllElLtl edges in pairs are brought into con tact with each other, which latter movement substantially takes place after the engage mcnt of the eyes with the head 20. This double movement is permitted by the universal joint 26.

If the plates 4 and 5 are not fully closed at the rear edges, a part of the water will pass through the opening thus formed. and the speed of the vessel is thereby regulated and even brought to zero, although the propeller rotates continuously.

in turning the wheel whilst the plates are open, the vessel can be steered simultaneously to the regulation of the speed.

In collapsing the opened rudder the handle 5S rotated in the opposite direction. The first n'iovemcnt of the crank 9 and the rod 10, Fig. 5', causes the slide T1 to slide rearwardly on the frame 6, whereby the links 12 and 13 open the rear contact: between the plates 4- and 5. The eyes 234 net-:1- come into contact with the head 20 and the plates are collapsed. the movements being contrary to those above mentioned in the description of the opening; of the plates. as is clearly apparent from the drawings.

As the head 20 can slide freely to a certain amount on the slide 11 (or eventually on the frame 6 directly), the plates auton'iatically, in opening or collapsing of rudder, take the positions. in which they made the least resistance to the movements.

Fig. 10 shows a slight modification of the steering transmission mechanism. The steering wheel is rigidly connected to the solar wheel 47 by means of a sleeve 61 and the handle 58 fixed to the solar wheel 49 by means of a sleeve 62. The handle 58 is fixed in position by a lever 63 pivotally mounted on it a i 64 and cooperating with a disc 55 fixed to a short shaft 66, which is immovably attached to a stationary part 67 of the vessel.

lac

The lever 63 is pressed to frictional contact against the disc 65 by means of a screw 68, and thereby the handle 58 is fixed. The rest of the mechanism is similar to that, shown in Fig. 9.
